MA40B8R Proximity Sensor circuit diagram

[Angelus]

Hi All,

After going through the forum I think I'm posting in the right place.

I have a couple of MA40B8R proximity sensors that I wanna use to detect distance. The thing is I looked everywhere for a circuit to make them work but didn't find any.

I can use IR to calculate distance, but I figured MA40B8R are more accurate.

Would you please provide me an implementation of those sensors?

Many thanks..
